A lens unit, a lens for a low-beam illumination module, a low-beam illumination module and a vehicle. The lens unit includes a rear surface and a front surface; the lens unit has a focal line, and the focal line is a straight line perpendicular to a light emitting direction of the lens unit; the rear surface and the front surface are adapted to project light rays passing through the focal line into parallel light rays, and the front surface is a free-form curved surface. The lens unit has the optical characteristics of a cylindrical lens, and is able to cause parallel incident light to be focused into a line instead of a focal point upon passing through the lens unit.

A chromaticity variable type road projection lamp system applied to a vehicle is composed of a chromaticity variable lamp that radiates a road surface radiation content, which is generated by reflecting the lights emitted from a first projection light-emitting diode (LED) of a warm white color and a second projection LED of a cool white color disposed in the direction symmetrical to a DMD at the tilting angle, with a projection beam from a chromaticity variable road projection, and radiates the low beam by comparing the warm white color of the first lamp LED and the cool white color of the second lamp LED with the road surface radiation content in chromaticity.

A luminous device including a first row of light sources for generating first unitary beams and a second row of light sources for generating second unitary beams. The first unitary beams have a sloped profile. The first unitary beams and second unitary beams are associated so as to construct a resultant beam provided with a slope and with a section extending laterally from the slope.

A bank angle of a vehicle can be accurately calculated using yaw axis data and roll axis data, and based on the calculated bank angle, vehicle illumination optics can be controlled to maintain a pattern of distributed light from the illumination optics to be generally horizontal. The calculated bank angle may be zeroed when the yaw axis data equals zero. The improved pattern of distributed light from the illumination optics illuminates a more natural field of view for the vehicle driver during a bank.

A lighting module includes a first light source that generates a low beam with a bright/dark cut-off line and a second light source. First optics redirects a first part of light from the first light source to create a main part of the low beam substantially below the bright/dark cut-off line. Second optics is spaced apart from the first optics and redirects a second part of light from the first light source to create a zone III beam of the low beam substantially above the bright/dark cut-off line and redirects a fourth part of light from the second light source to create a concentrated beam of the high beam in front of the vehicle. Third optics redirects a third part of light from the second light source to create a main part of a high beam.

The invention relates to a lighting module, in particular for a motor vehicle, including a main optical system able to form a main light beam along an optical axis of the lighting module, with an upper horizontal cut-off. A first complementary optical system able to form a first complementary light beam along the optical axis, narrower than the main light beam and with an oblique lateral cut-off. A second complementary optical system able to form an alternative, second complementary light beam along the optical axis, narrower than the main light beam and with an oblique lateral cut-off opposite the oblique lateral cut-off of the first complementary light beam.

A vehicle headlight (1) includes a first lamp unit (10) that includes a light distribution pattern forming unit (12) which forms a predetermined light distribution pattern (P1) according to the light amount of the light emitted from a plurality of light emitting elements (13), and a second lamp unit (20), in which a light distribution pattern (PL) of a low beam is formed by light emitted from the first lamp unit (10) and light emitted from the second lamp unit (20), and in the light distribution pattern (PL) of the low beam, the elbow point (EP) is included in a predetermined region (CA) formed by light including the light from the first lamp unit (10), and a first side region (SA1) and a second side region (SA2) sandwiching the predetermined region (CA) are formed by the light emitted from the second lamp unit (20).

It is an object to provide a motor vehicle headlight assembly that includes a headlight module having a first luminous intensity distribution, a first additional headlight module having a second luminous intensity distribution different from the first luminous intensity distribution, and a control circuit. The control circuit may be configured to apply power to the headlight module based on one or more of a switch input and a light/dark input, and apply power to the first additional headlight module when a speed of the motor vehicle exceeds a first predetermined threshold.

A lighting module for a motor vehicle headlight intended to produce a low beam having an at least partly oblique cut-off. This same module further comprises an additional lighting function making it possible to generate a high type beam, the dimensions of the lighting module remaining identical. The light sources of the two respective low and high beam functions are arranged in a vicinity of the focus of an optical portion of the module such that the lighting module remains compact.

A light unit is configured in such a manner that a light guide is placed between a light source and a projection lens, and includes a first exit surface for emitting light for a low-beam light distribution pattern and a second exit surface for emitting light for an additional light distribution pattern that is added to form a high-beam light distribution pattern. The light guide is configured to be provided with a mirror surface portion on a connection surface extending toward the back of the unit from a lower edge of the first exit surface to an upper edge of the second exit surface. As a result, light from a light-emitting element that has been emitted through the second exit surface and reached the connection surface is reflected by the mirror surface portion to be used as the light for forming the additional light distribution pattern.
